Additional information

Protection

Over-load (e.g. pump jammed)
Under-load (e.g. run-dry)
Over-Voltage
Under-Voltage
Phase Failure (e.g. a wire is cut)
Phase sequence changes (e.g. after a power failure, the phases are swapped)
Phase Imbalance (e.g. one of the phases carries more load than the other two)
Not against lightning

Features

LEVEL CONTROL: Filling or Emptying, Float Switches or Probes, Manual or Auto.

TWO ALARM RELAYS: The two Supras share an alarm output for: Over Current, Over Power, Minimum Phase Angle, No Current and Uncalibrated. Shared level and pump alarm output for: Either high or Low level, Oil sump water detection, Controller Error.

RECOVERY TIMERS: Each Supra has its own Recover Timer to allow the sump to fill up before a restart attempt is made (after a run-dry condition). These timers are manually adjustable from 4 minutes to 16 hours.

REAL-TIME CLOCK: Each Supra has a real-time clock. This allows each unit to store the date and time (year, month, day, hour, minute) of each one of the last 43 trips.

Built-in User Interface Options

The S2LC has a dedicated serial port for each Supra to which the following Built-in User interface options could be connected:

– A single Mobi Board (Bluetooth Interface to App) which can manually be moved from one Supra’s serial port to the other.

– Two Mobi Boards (one for each Supra)

– A single Built-in Optimizer which can manually be moved from the one Supra’s serial port to the other Unfortunately the Built-in optimizers are too big to allow two of them to fit into each-other on the S2LC therefore no dual Built-In Optimizer option is available.
